本發明有關軌道膨脹裝置及用於補償設計用於導引被引導車輛的軌道之膨脹的方法。The invention relates to a rail expansion device and a method for compensating for the expansion of a rail designed to guide guided vehicles.

本發明本質上有關導引車輛之領域，其中「導引車輛」一詞意指公共交通工具，諸如地鐵、火車、或火車子單元、公共汽車等，其構造成用於運輸乘客且其安全性是非常重要的因素。此等被導引車輛通常藉由至少一條軌道、通常是兩條軌道沿著路線或鐵路導引。更明確地是，本發明有關軌道膨脹裝置、亦已知膨脹接頭，其係安裝在必需補償二軸向直接相鄰軌道之間的相對縱向移動之區域中。此相對移動可源自軌道擴張/收縮、或源自於其中安裝軌道的橋樑結構與支撐軸向直接相鄰之軌道的道碴之間的相對移動。The present invention pertains essentially to the field of guided vehicles, where the term "guided vehicle" means public transport means, such as subways, trains, or sub-units of trains, buses, etc., which are constructed to transport passengers and whose safety is a very important factor. These guided vehicles are usually guided along a route or railway by means of at least one track, usually two tracks. More specifically, the invention relates to rail expansion devices, also known as expansion joints, which are installed in areas where it is necessary to compensate for relative longitudinal movements between two axially directly adjacent rails. This relative movement may result from track expansion/contraction, or from relative movement between the bridge structure in which the track is installed and the ballast supporting the axially directly adjacent track.

本發明尤其有關包含藉由安裝在軌道上之單一鐵軌所導引的導引單元之導引車輛。當導引車輛於所述軌道上移動時，導引單元順著藉由該單一軌道所界定的軌線。導引單元例如能夠使導引車輛導引系統沿著所述軌線引導被導引車輛轉向軸，以致所述導引車輛不離開其軌道，保持藉由鐵軌所界定之軌線。通常所述轉向軸裝有轉向架輪。The invention relates in particular to a guided vehicle comprising a guiding unit guided by a single rail mounted on a track. When the guiding vehicle moves on said track, the guiding unit follows the trajectory defined by the single track. The guiding unit enables, for example, the guiding vehicle guiding system to guide the steering axis of the guided vehicle along said trajectory, so that said guiding vehicle does not leave its track, maintaining the trajectory defined by the rails. Usually the steering shaft is fitted with bogie wheels.

即使導引單元不是本發明的一部分，對所述導引單元之簡短敘述將有助於理解本發明：Even though the guiding unit is not part of the invention, a short description of said guiding unit will help to understand the invention:

導引單元大致上包括一對導引輪，亦稱為導引滾輪，安裝在V形部中並配備有凸緣，使其可能夾住軌道。此導引單元例如敘述於文件US 7,228,803 B2或US 6,029,579 A1中。藉由此類型導引單元所導引的車輛根據參考圖1所敘述之以下一般原理來操作：所述導引單元藉著一對與軌道3接觸的滾輪1、2順著軌道3並為導引系統給與強加在導引車輛之轉向軸上的方向。適於導引此導引車輛之軌道3通常由固定至地面5的底板4及支撐頭部7之芯部6製成，滾輪1、2係經由輪面9支撐在頭部7上。因此，於相同對導引滾輪中的每一個滾輪1、2具有其與頭部7之表面接觸的輪面9，頭部7的表面稱為運行表面7a、7b，並對稱地分佈在頭部7之上部的每一側上。當車輛移動時，滾輪1、2係與頭部7接觸，且它們之各自凸緣10在標稱模式下無接觸地環繞頭部，並較接近於其下方的芯部6。如果固定滾輪之角度11、亦即對應於藉由一對導引滾輪的每一個滾輪1、2之旋轉軸線所形成的扇形區及藉由V形部中之導引滾輪對的對稱平面所切割之角度增加，及/或如果凸緣10及/或頭部7的外緣變形，由於環繞頭部7之二凸緣10的下端201、101之間的距離小於頭部7之寬度W，頭部7僅由所述滾輪1、2的夾住中抽出、或甚至由輪面9與凸緣10之間所包括的區域抽出係可能的。The guide unit consists essentially of a pair of guide wheels, also called guide rollers, mounted in a V-shaped section and equipped with flanges making it possible to grip the rail. Such guiding units are described, for example, in documents US 7,228,803 B2 or US 6,029,579 A1. A vehicle guided by a guide unit of this type operates according to the following general principle described with reference to FIG. The guidance system gives the direction imposed on the steering axis of the leading vehicle. The track 3 suitable for guiding this guided vehicle is usually made of a base plate 4 fixed to the ground 5 and a core 6 supporting a head 7 on which the rollers 1 , 2 are supported via a wheel surface 9 . Therefore, each roller 1, 2 in the same pair of guide rollers has its wheel surface 9 in contact with the surface of the head 7, which is called the running surface 7a, 7b and is symmetrically distributed in the head 7 on each side of the upper part. When the vehicle is moving, the rollers 1, 2 are in contact with the head 7 and their respective flanges 10 surround the head in nominal mode without contact and are closer to the core 6 below it. If the angle 11 of the fixed rollers, that is, corresponds to the sector formed by the axis of rotation of each roller 1, 2 of a pair of guide rollers and cut by the plane of symmetry of the pair of guide rollers in the V-shaped section The angle increases, and/or if the outer edge of flange 10 and/or head 7 is deformed, because the distance between the lower ends 201,101 of two flanges 10 around head 7 is less than the width W of head 7, the head It is possible to extract the portion 7 only from the clamping of said rollers 1 , 2 , or even from the area comprised between the wheel surface 9 and the flange 10 .

因此，藉由將導引系統之導引單元的導引滾輪對與導引車輛之轉向軸耦接來獲得此車輛的正確定向。如果滾輪正確地夾住軌道3，則導引車輛當其移動時順著藉由軌道3所敘述之軌線。Thus, the correct orientation of the vehicle is obtained by coupling the pair of guide rollers of the guidance unit of the guidance system with the steering shaft of the guiding vehicle. If the rollers grip the track 3 correctly, the vehicle is guided to follow the trajectory described by the track 3 as it moves.

On the opposite side, the contraction of the first track will increase the width D of the expansion gap G. Said variable width D of the expansion gap G thus enables the track expansion device 30 to compensate for any longitudinal relative movement of the first end F1 with respect to the second end R2. The maximum value D'' for the width D of the expansion gap G is for example comprised between 100 mm and 200 mm, preferably 150 mm.

當由第一軌道移動至第二軌道時，導引滾輪將首先在其前端FE1處遇到前連接軌道之頭部的運行表面，其中，尤其是由於它們之橫截面的完全相同之外部形狀，第一軌道及前連接軌道的頭部之運行表面具有完全相同的寬度且相互為連續的。前連接軌道之頭部的運行表面接著由前端FE1連續地延伸直至後端RE1，其中所述頭部係藉由前拼合件310之形狀所界定。所述形狀構造成沿著前拼合件310的整個縱向長度提供運行表面之連續性(亦即滾輪始終與軌道頭部接觸)，直至抵達在前端FE2界定後連接軌道32的軌道頭部之形狀的後拼合件320。藉由後拼合件320所界定之軌道頭部的所述形狀構造成確保所述運行表面由在所述前端FE2處之前拼合件310直至後端RE2的連續性，其中第二軌道頭部及後連接軌道頭部於所述後端RE2處之運行表面具有完全相同的寬度且係彼此連續的。例如，後連接軌道之特徵在於，在其後端RE2，軌道頭部的橫截面外部形狀較佳為與第二軌道橫截面之外部形狀相同，因此確保運行表面由後端RE2直至第二軌道的連續性。藉由運行表面之連續性，本發明意指相鄰/連續的運行表面位於相同平面中且具有共同之線或邊緣，以致當由一運行表面通過至另一相鄰/連續的運行表面時、或當同時於二相鄰/連續之運行表面上運行時，在所述運行表面上移動的滾輪將不會遇到間隙。When moving from the first rail to the second rail, the guide rollers will firstly meet at their front end FE1 the running surface of the head of the front connecting rail, wherein, in particular due to the identical external shape of their cross-section, The running surfaces of the first rail and the head of the front connecting rail have exactly the same width and are continuous with each other. The running surface of the head of the front connecting rail then extends continuously from the front end FE1 to the rear end RE1 , wherein said head is defined by the shape of the front split piece 310 . The shape is configured to provide continuity of the running surface (i.e. the rollers are always in contact with the track head) along the entire longitudinal length of the front split piece 310 until reaching the shape of the track head connecting the track 32 after the front end FE2 is defined. Rear split 320 . The shape of the rail head defined by the rear split 320 is configured to ensure the continuity of the running surface from the front split 310 at the front end FE2 to the rear end RE2, wherein the second rail head and the rear The running surfaces of the connecting rail heads at said rear end RE2 have exactly the same width and are continuous with each other. For example, the rear connecting rail is characterized in that, at its rear end RE2, the cross-sectional outer shape of the rail head is preferably identical to the outer shape of the second rail cross-section, thus ensuring a running surface from the rear end RE2 to the second rail's outer shape. continuity. By the continuity of running surfaces, the present invention means that adjacent/continuous running surfaces lie in the same plane and have a common line or edge, so that when passing from one running surface to another adjacent/continuous running surface, Or when running on two adjacent/contiguous running surfaces at the same time, the rollers moving on said running surfaces will not encounter a gap.

因此，軌道膨脹裝置之上述特徵確保由第一軌道至第二軌道的導引滾輪運行表面之連續性。較佳地，於軌道頭部的橫截面中所測量之所述運行表面RS的寬度絕不會小於在此橫截面中所測量之第一或第二軌道的標稱運行表面之寬度的一半。實際上，當導引滾輪抵達前拼合件310時，它將擱置於其寬度藉由橫截面C1(參見圖4)所界定之運行表面上：當考量橫截面C1時，將在第一或第二軌道的橫截面上測量之運行表面RS的每一者之運行表面寬度RSW及每一標稱運行表面的寬度都是相等的。換句話說，頂部312之基底部分312B包含運行表面RS，每一運行表面RS的特徵在於當在所述第一或第二軌道上移動時，寬度RSW等於滾輪將接觸之第一或第二軌道的運行表面之寬度。當導引滾輪進一步在第二軌道的方向中移動時，它將在位於開口310A上方之運行表面上運行(這尤其對應於膨脹間隙G的寬度D之值具有大於D'的值之情形)，且其寬度係藉由橫截面C2所界定或在其寬度係藉由橫截面C3所界定的運行表面上運行(這尤其對應於膨脹間隙G具有寬度D=D'之情形，亦即其最小值，例如D'=0)。橫截面C2通過開口310A，亦即當膨脹間隙G的寬度D係大於D'時，頂部312橋接開口310A，使其底部312B擱置並固定至底部311及使其第一突出構件312A擱置及/或滑動在後拼合件320上。於此情形中，橫截面C2包含底部分311之橫截面及第一突出構件312A的橫截面，使開口310A佈置在它們之間，並構造成在膨脹間隙G減小期間收容第三突出構件320A。如圖12中所例示，第一突出構件312A的橫截面包含如先前所述之一對運行表面RS，其中所述運行表面RS的每一者之寬度RSW較佳為標稱運行表面的寬度之一半，滾輪當於第一或第二軌道上運行時接觸標稱運行表面。實際上，且如橫截面C3及C4中所顯示，第一突出構件312A包含標稱運行表面的寬度之一半，且後拼合件320的重疊部分、亦即所述第一可變部分較佳包含如藉由第一或第二軌道所界定之標稱運行表面的寬度之另一半。因此，只要創建開口310A，例如由於膨脹間隙G的寬度D之增加，第一突出構件312A將橋接所創建的開口310A，因此軌道膨脹裝置之特徵在於軌道頭部橫截面C2，其以由基底部分312B直至第一突出構件312A進入與後拼合件320接觸的點之軌道膨脹裝置為特徵，其中在所述接觸點處的橫截面界定如橫截面C3或C4中所例示之運行表面RS，亦即，其寬度係藉由第一突出構件312A所界定的運行表面寬度及藉由構造成所述第一突出構件312A所重疊之後拼合件的部分所界定之運行表面寬度的總和，因此所述總和導致總運行表面寬度等於標稱運行表面寬度。實際上，後拼合件320較佳為界定二完全相同之運行表面RS，它們如先前所解釋那樣對稱地佈置在中間平面M的每一側面上，且其特徵在於橫截面中所測量之寬度係標稱運行表面的寬度之一半，如橫截面C3-C5中所顯示。當藉由第一突出構件312A所重疊時，如藉由橫截面C3及C4所例示，後拼合件320的運行表面RS之寬度增加了第一突出構件312A的運行表面之寬度，以致對於藉由第一突出構件312A所重疊的後拼合件之所有長度，所得寬度等於所述標稱寬度。未藉由第一突出構件312A重疊的後拼合件320之任何剩餘縱向長度將接著以等於標稱運行表面寬度的一半之運行表面寬度RSW為特徵，如橫橫截面C5中所顯示。 Thus, the above-mentioned features of the track expansion device ensure the continuity of the running surfaces of the guide rollers from the first track to the second track. Preferably, the width of said running surface RS measured in a cross-section of the rail head is never less than half the width of the nominal running surface of the first or second rail measured in this cross-section. In fact, when the guide roller reaches the front split 310, it rests on a running surface whose width is defined by the cross-section C1 (see FIG. 4 ): The running surface width RSW of each of the running surfaces RS measured on the cross-section of the two tracks and the width of each nominal running surface are equal. In other words, the base portion 312B of the top 312 comprises running surfaces RS each characterized by a width RSW equal to the first or second track that the rollers will contact when moving on said first or second track The width of the running surface. When the guide roller moves further in the direction of the second track, it will run on the running surface located above the opening 310A (this corresponds in particular to the case where the width D of the expansion gap G has a value greater than D'), and its width is defined by the cross-section C2 or runs on a running surface whose width is defined by the cross-section C3 (this corresponds in particular to the case where the expansion gap G has a width D=D', i.e. its minimum , eg D'=0). The cross-section C2 passes through the opening 310A, i.e. when the width D of the expansion gap G is greater than D′, the top 312 bridges the opening 310A, rests and fixes its bottom 312B to the bottom 311 and its first protruding member 312A and/or Slide on rear panel 320 . In this case, the cross-section C2 includes the cross-section of the bottom portion 311 and the cross-section of the first protruding member 312A, with the opening 310A disposed therebetween and configured to receive the third protruding member 320A during the reduction of the expansion gap G . As illustrated in FIG. 12 , the cross-section of the first protruding member 312A comprises a pair of running surfaces RS as previously described, wherein the width RSW of each of the running surfaces RS is preferably less than the width of the nominal running surface. Halfway, the roller contacts the nominal running surface when running on the first or second track. In practice, and as shown in cross-sections C3 and C4, the first protruding member 312A comprises half the width of the nominal running surface, and the overlapping portion of the rear sectional piece 320, ie the first variable portion preferably comprises The other half of the width of the nominal running surface as defined by the first or second track. Thus, as soon as the opening 310A is created, for example due to an increase in the width D of the expansion gap G, the first protruding member 312A will bridge the opening 310A created, so the track expansion device is characterized by a track head cross-section C2 which is defined by the base part 312B until the point where the first protruding member 312A enters contact with the rear split piece 320 is characterized by a cross-section at the point of contact defining a running surface RS as exemplified in cross-section C3 or C4, i.e. , whose width is the sum of the width of the running surface defined by the first protruding member 312A and the width of the running surface defined by the portion of the split piece configured to overlap the first protruding member 312A, so that the sum results in The total running surface width is equal to the nominal running surface width. In practice, the rear split 320 preferably defines two identical running surfaces RS, symmetrically arranged on each side of the median plane M as previously explained, and characterized in that the width measured in cross-section is One-half the width of the nominal running surface, as shown in cross-sections C3-C5. When overlapped by the first protruding member 312A, as illustrated by cross-sections C3 and C4, the width of the running surface RS of the rear sectional piece 320 increases the width of the running surface of the first protruding member 312A such that for For all lengths of the rear sectional overlapped by the first protruding member 312A, the resulting width is equal to the nominal width. Any remaining longitudinal length of the rear sectional 320 not overlapped by the first protruding member 312A will then be characterized by a running surface width RSW equal to half the nominal running surface width, as shown in cross-section C5.

總而言之，前拼合件310、以及後拼合件320包含在其整個長度上的運行表面RS，其中於橫截面中所測量之每一所述運行表面RS的寬度較佳為至少等於將接觸在第一或第二軌道上移動之滾輪的運行表面之寬度的一半。 In summary, the front split piece 310, and the rear split piece 320 comprise running surfaces RS over their entire length, wherein the width of each said running surface RS measured in cross-section is preferably at least equal to the Or half the width of the running surface of the rollers moving on the second track.

另外，如圖12中所顯示及先前所解釋，藉由根據本發明之軌道膨脹裝置所界定的軌道頭部之寬度W由前端FE1直至後端RE2保持恆定，且較佳係等於第一或第二軌道的軌道頭部寬度。軌道頭部之寬度係垂直於中間平面M測量、亦即在如圖12中所例示的橫截面內測量。尤其是，後拼合件320之特徵在於恆定的最大寬度等於所述第一或第二軌道頭部寬度。較佳地，頂部312之基底部分312B的特徵在於最大寬度構造成界定其寬度W等於所述第一或第二軌道頭部寬度之軌道頭部。尤其是，第一突出構件312A的特徵在於最大寬度W'小於第一或第二軌道頭部寬度，如圖12之橫截面C2中所顯示。然而，既然第一突出構件312A總是位於軌道膨脹裝置的至少另一部分上方，其特徵在於寬度等於第一或第二軌道之軌道頭部寬度，所述另一部分例如係底部 311及/或後拼合件320，它確保所述第一突出部分312A及所述另一部分一起界定等於第一或第二軌道頭部寬度的軌道頭部寬度。值得注意的是，底部311之構造成藉由第三突出構件320A重疊的縱向部分之顯著特徵在於恆定寬度等於第一或第二軌道頭部寬度。 In addition, as shown in FIG. 12 and previously explained, the width W of the track head defined by the track expansion device according to the invention remains constant from the front end FE1 to the rear end RE2 and is preferably equal to the first or second The width of the track header for the second track. The width of the rail head is measured perpendicular to the median plane M, ie in cross-section as illustrated in FIG. 12 . In particular, rear split 320 is characterized by a constant maximum width equal to said first or second rail head width. Preferably, the base portion 312B of the top 312 is characterized by a maximum width configured to define a track header having a width W equal to said first or second track header width. In particular, the first protruding member 312A is characterized by a maximum width W' that is less than the first or second rail head width, as shown in cross-section C2 of FIG. 12 . However, since the first protruding member 312A is always located above at least another portion of the track expansion device, characterized by a width equal to the width of the track head of the first or second track, such as the bottom 311 and/or rear split piece 320, which ensures that said first protruding portion 312A and said further portion together define a track header width equal to the first or second track header width. It is worth noting that the distinctive feature of the longitudinal portion of the bottom 311 configured to be overlapped by the third protruding member 320A is a constant width equal to the first or second track head width.

根據藉由圖11所例示的較佳實施例，僅底部311及頂部312構造成橋接膨脹間隙G，尤其是當以其最大寬度值D"為特徵時，而使一側面藉由前連接軌道所支撐，且另一側面藉由後連接軌道所支撐，而後拼合件320不會延伸超出前端FE2之端部。底部311係固定至前連接軌道31的本體/結構，並包含突出末端、亦即所述第二突出構件311A，構造成當第一軌道及第二軌道移離彼此時橋接所述膨脹間隙G，所述第二突出構件311A係滑動地安裝在所述第二開口321A內之第二連接軌道的本體/結構上，因此夾在第二連接軌道的本體/結構與第三突出構件320A之間。較佳地，當膨脹間隙G處於其最小值處而以寬度D'為特徵時，底部311的所述第二突出構件311A接觸後拼合件320之基底部分320B。取決於第三突出構件320A的長度及其是否橋接膨脹間隙G，第一開口310A可為位於膨脹間隙G上方(參見圖4)，或可保持位於後端RE1上方(參見圖3)，或亦可為位於前端FE2上方(未顯示)。在每一情形中，第三突出構件320A較佳為夾在底部311與頂部312之間，而滑動地安裝於第一開口310A內。當膨脹間隙G處於其最小值處而以寬度D'為特徵時，較佳具有D'=0，所述第一開口310A及所述第二開口321A較佳為關閉。According to the preferred embodiment illustrated by FIG. 11, only the bottom 311 and the top 312 are configured to bridge the expansion gap G, especially when characterized by their maximum width value D", so that one side is defined by the front connecting rail. and the other side is supported by the rear connecting track, and the rear split piece 320 does not extend beyond the end of the front end FE2. The bottom 311 is fixed to the body/structure of the front connecting track 31 and includes the protruding end, which is the The second protruding member 311A is configured to bridge the expansion gap G when the first rail and the second rail move away from each other, the second protruding member 311A is a second protruding member slidably mounted in the second opening 321A. on the body/structure of the connecting rail, and thus sandwiched between the body/structure of the second connecting rail and the third protruding member 320A. Preferably, when the expansion gap G is at its minimum, characterized by a width D', The second protruding member 311A of the bottom 311 contacts the base portion 320B of the rear split 320. Depending on the length of the third protruding member 320A and whether it bridges the expansion gap G, the first opening 310A may be located above the expansion gap G (see Fig. 4), or may remain above the rear end RE1 (see Fig. 3), or may also be positioned above the front end FE2 (not shown). In each case, the third protruding member 320A is preferably sandwiched between the bottom 311 and between the tops 312 and is slidably mounted in the first opening 310A. When the expansion gap G is at its minimum and is characterized by a width D', preferably with D'=0, the first opening 310A and the The second opening 321A is preferably closed.

如圖11及12中所顯示，前拼合件的頂部312包含構造成強化第一突出構件312A之剛性的強化結構313。較佳地，所述強化結構313縱向地延伸在第一突出構件312A之整個長度上，並可選地進一步於一方向中及在基底部分312B上延伸。所述強化結構313可為藉著任何固定手段固定至頂部312，或可為藉由機械加工所獲得，亦即頂部312及其強化結構313係單一且相同的組件。根據為正且較佳包含於5-20毫米之間的高度H，具有15毫米為較佳之值，此強化結構313在第一突出構件312A之頂部上、或可選地於前拼合件310的頂部上垂直地延伸，所述強化結構之頂部表面相對於第一或第二軌道頭部之頂部表面的標稱位準界定位在額外高度處之上位準。As shown in Figures 11 and 12, the top 312 of the front sectional piece includes a reinforcement structure 313 configured to reinforce the rigidity of the first protruding member 312A. Preferably, the reinforcing structure 313 extends longitudinally over the entire length of the first protruding member 312A, and optionally further extends in one direction and over the base portion 312B. The reinforcing structure 313 may be fixed to the top 312 by any fixing means, or may be obtained by machining, ie the top 312 and its reinforcing structure 313 are a single and identical component. This reinforcing structure 313 is on top of the first protruding member 312A, or optionally at the front part 310, according to a height H that is positive and preferably comprised between 5-20 mm, with a preferred value of 15 mm. Extending vertically on top, the top surface of the stiffening structure is defined at an upper level at an additional height relative to the nominal level of the top surface of the first or second rail head.

因此，由軌道基底至其軌道頭部的頂部所垂直地測量之軌道的總高度當於第一或第二軌道之橫截面中、或在如圖12所顯示的橫截面中測量時不會相同。為了補償此高度差、亦即源自強化結構313之附加高度H，根據本發明的軌道膨脹裝置30更包含前斜面314及後斜面315，此等斜面構造成將導引單元的接觸塊由第一或第二軌道之軌道頭部的頂部表面之標稱位準導引至強化結構的所述上位準，所述上位準相對於標稱位準位在所述額外高度處。Therefore, the overall height of the track, measured perpendicularly from the base of the track to the top of its track head, will not be the same when measured in cross-section of the first or second track, or in cross-section as shown in Figure 12 . In order to compensate for this height difference, that is to say the additional height H resulting from the reinforcing structure 313, the track expansion device 30 according to the invention further comprises a front slope 314 and a rear slope 315, which are configured to move the contact block of the guide unit from the first The nominal level of the top surface of the rail head of one or the second rail leads to said upper level of the reinforcement structure at said extra height relative to the nominal level.

The front slope 314 has a basic shape configured as a bar extending from the front split piece toward the front end FE1 of the front connecting rail 31 . The front ramp 314 is preferably fixed to the front connecting rail 31 and the front split piece 310 by any known fixing means like screws. The front ramp 314 includes a top surface 314S intended to support the slider of the guide unit, which extends from a front end FER1 configured to be fixed to the front connecting rail to a rear end RER1 configured to be fixed to the front split piece 310 . Preferably, the front connecting rail 31 comprises a longitudinal slot or groove 31S (see FIGS. 6 and 9 ) extending longitudinally at the top of its rail head and configured to receive said front bevel 314 (see FIGS. 6 and 9 ), wherein when assembled closer to the front 310, the depth of the slot or groove 31S is reduced so that the top surface 314S of the front end FER1 of the front bevel 314 is at the nominal level of the top surface of the rail head of the first or second rail, and The top surface 314S of the rear end RER1 is at a level above the reinforcing structure 313 . The top surface 314S thus defines an inclined plane from the nominal level of the rail head to the upper level of the top surface of the strengthening structure 313 .

後斜面315具有實質上構造成由後拼合件320朝後連接軌道32的後端RE2延伸之桿棒的形狀。所述後斜面315較佳係藉由像螺絲的任何已知之固定手段固定至後連接軌道31。所述後斜面315與後拼合件320沒有任何固定手段。較佳地，它包含突出部分315P(參見圖11及圖14)，其構造成朝第一突出構件312A延伸並在位於第一突出構件312上方的強化結構313中所佈置之長孔或溝槽313S內滑動(參見圖12，截面T，或圖11)。此突出部分315P能夠將後斜面315可滑動地連接至前拼合件310，以便補償膨脹間隙G的寬度D之變動。後斜面315包含意欲支撐導引單元的滑塊之頂部表面315S，所述頂部表面315S由構造成被固定至後連接軌道的後端RER2延伸至包含所述突出部分315P並構造成接觸前拼合件310之前末端FER2。後連接軌道32較佳包含在其軌道頭部的頂部縱向地延伸並構造成***述後斜面315之縱向長孔或溝槽32S(參見圖10)，其中當更靠近後拼合件320時，所述長孔或溝槽32S的深度減小，以致後斜面315之後末端RER2的頂部表面315S位於第一或第二軌道之軌道頭部的頂部表面之標稱位準處，且前末端FER2的頂部表面315S位於強化結構313之上位準處。頂部表面315S因此界定由軌道頭部的標稱位準至強化結構313之頂部表面的上位準之傾斜平面。The rear slope 315 has a shape substantially configured as a rod extending from the rear split piece 320 toward the rear end RE2 of the rear connection rail 32 . The rear ramp 315 is preferably fixed to the rear connecting rail 31 by any known fixing means like screws. The rear bevel 315 and the rear split piece 320 do not have any fixing means. Preferably, it comprises a protruding portion 315P (see FIGS. 11 and 14 ) configured as a slot or groove extending towards the first protruding member 312A and disposed in the reinforcing structure 313 above the first protruding member 312 Slide in 313S (see Figure 12, Section T, or Figure 11). This protruding portion 315P is capable of slidably connecting the rear ramp 315 to the front split piece 310 so as to compensate for variations in the width D of the expansion gap G. The rear ramp 315 includes a top surface 315S intended to support the slider of the guide unit, said top surface 315S extending from the rear end RER2 configured to be fixed to the rear connecting rail to include said protruding portion 315P and configured to contact the front split 310 before the terminal Fer2. The rear connecting rail 32 preferably includes a longitudinal slot or groove 32S (see FIG. 10 ) extending longitudinally at the top of its rail head and configured to receive the rear ramp 315 (see FIG. 10 ), wherein when closer to the rear split 320, The depth of the slot or groove 32S is reduced so that the top surface 315S of the rear end RER2 of the rear bevel 315 is at the nominal level of the top surface of the rail head of the first or second track, and the top surface of the front end FER2 The top surface 315S is at a level above the reinforcement structure 313 . The top surface 315S thus defines an inclined plane from the nominal level of the rail head to the upper level of the top surface of the strengthening structure 313 .
